Interim status report of continuing program to reduce perceived noise levels (PNL's) on ground below takeoff and landing approach paths of turbofan-powered commercial transports; program is directed principally toward development of fan-inlet and exhaust ducts incorporating acoustically absorptive linings; ground and flight tests have been performed on experimental design evolved by incorporating linings within basic "short" fan-discharge duct design of transport aircraft; results obtained show that improved lining designs are needed to provide acceptable service life; summaries of experimental and analytical studies conducted concurrent with design, fabrication, and testing of experimental ducts are also presented.
